Garagiola's successor, Josh Byrnes, though, has been more cooperative. He and Towers worked out a second trade this month, one that will bring first baseman/pinch-hitter Tony Clark to San Diego Monday night in a Diamondbacks uniform.

Hairston's home run handed Bell a 2-1 lead and was his 25th in 361 at-bats for the Padres. He hit three on the trip.

After Bell retired the three batters he faced, Trevor Hoffman set down three in a row to pick up his third save in three games and 21st in 24 attempts this season, moving his conversion rate this season to 87.5 percent, close to his career mark (89.3).

In the series, Hoffman retired all seven batters he faced in PNC Park, where the Padres improved to 17-8. The three-game winning streak is their first since June 6-8, when the Padres completed a four-game sweep of the Mets in San Diego.
